FBAR Violations for Crypto Accounts: $100,000 Penalties Explained
If you hold cryptocurrency on a foreign exchange and didn’t file an FBAR, you could be facing a $100,000 penalty. It’s not a rumor. It’s not a scare tactic. It’s happening right now.
The Foreign Bank Account Report (FBAR) isn’t just for Swiss bank accounts anymore. Since 2023, the IRS and FinCEN have been moving to explicitly include cryptocurrency held overseas as a reportable foreign financial account. And if you missed the deadline-or didn’t even know you had to file-you’re at risk.
What Is an FBAR, Really?
The FBAR, or FinCEN Form 114, is a report you must file if you had more than $10,000 in aggregate foreign financial accounts at any time during the year. It’s not part of your tax return. It’s a separate form filed directly with the Financial Crimes Enforcement Network (FinCEN), a division of the U.S. Treasury.
Before 2023, the rules were murky. Many people assumed that if their crypto was on a foreign exchange like Binance, Kraken, or Bybit, it didn’t count. That assumption is now dangerous. FinCEN published a rulemaking notice in June 2023 that explicitly proposed including virtual currency accounts under FBAR rules. By late 2024, enforcement began. The first court case, USA v. John Doe, was filed in January 2024, seeking $100,000 in penalties for unreported Binance holdings.
Who Has to File?
You must file if you’re a U.S. person-citizen, green card holder, resident alien, or even a U.S.-based corporation or trust-and you had more than $10,000 in total value across all your foreign accounts during the year. That includes:
- Foreign cryptocurrency exchanges (like Binance, Kraken, Bitstamp)
- Foreign wallets where you don’t control the private keys
- Foreign bank accounts holding crypto
- Foreign brokerage accounts with crypto holdings
It doesn’t matter if the account only hit $10,001 for one day. You still have to report it. And you must combine all your foreign accounts. So if you had $6,000 in BTC on Binance and $5,000 in ETH on Kraken, you’re over the $10,000 threshold.
What’s the Penalty?
There are two types of violations: non-willful and willful.
Non-willful means you didn’t know you had to file. Maybe you thought crypto didn’t count. The penalty for non-willful violations is capped at $16,536 per year as of 2025. That’s still a lot-but it’s manageable if you come forward.
Willful means the IRS believes you knew you had to file and chose not to. That’s where the $100,000 penalty comes in. Or, if your account balance was higher, you could owe 50% of the highest value in that account during the year. Whichever is higher.
And here’s the scary part: the Supreme Court’s Bittner decision in 2023 changed how penalties are calculated. Before, the IRS could charge $10,000 per unreported account. Now, it’s $100,000 per report you failed to file. So if you had five foreign crypto accounts and didn’t file for 2021, you could be hit with one $100,000 penalty-not five separate ones. But if you didn’t file for 2021, 2022, and 2023? That’s three separate $100,000 penalties.
Why This Is a Big Deal Right Now
The IRS has been quietly building a system to catch crypto users. Since 2022, major foreign exchanges like Binance, Kraken, and Coinbase International have started collecting U.S. taxpayer ID numbers. They’re required to report this data under FATCA treaties with over 110 countries. The IRS doesn’t need your permission to see your account balances anymore.
In 2023, the IRS’s Large Business and International division flagged cryptocurrency as a “high-risk compliance area.” Their 2024-2026 Strategic Plan says they’re doubling down on foreign crypto enforcement. And the numbers show why: FBAR penalties brought in $340 million in 2023. By 2026, that’s projected to hit $890 million.
Meanwhile, tax software companies are racing to catch up. TurboTax added crypto FBAR reporting in March 2024. TaxAct followed with its CryptoPro module. But most people still don’t know they need it.
What People Get Wrong
Based on surveys from 2024, here’s what most crypto holders misunderstand:
- “I didn’t sell any crypto, so I don’t owe anything.” FBAR has nothing to do with capital gains. It’s about ownership and location.
- “I only had crypto on a U.S.-based exchange.” If the exchange is legally based outside the U.S. (like Binance.com, not Binance.US), it counts.
- “I didn’t know crypto counted.” Ignorance isn’t a defense. The IRS considers this negligence, not innocence.
- “I only had $8,000 in crypto.” Combine it with your foreign bank account, investment account, or other crypto holdings. $8,000 + $3,000 = $11,000. You’re over.
A Reddit user named u/CryptoTaxConfused posted in February 2024: “I had $15k in Binance US but didn’t realize my foreign Binance account with $8k in BTC also needed reporting-now I’m terrified of penalties.” That’s exactly the kind of mistake that leads to $100,000 penalties.
How to Fix It If You Didn’t File
It’s not too late. The IRS has programs to help people come clean.
Streamlined Filing Compliance Procedures let you file missing FBARs and tax returns with reduced or zero penalties if you can show your failure was non-willful. You’ll need to file the last six years of FBARs and the last three years of tax returns, plus a statement explaining why you didn’t file before.
Delinquent FBAR Submission Procedures are for people who only missed FBARs but are otherwise compliant. You file the missing forms with a reasonable cause statement. No penalty if you can prove you didn’t know.
One Reddit user, u/CompliantCryptoTrader, filed amended FBARs for 2020-2023 after seeing a warning from Bitwave.io. He included a detailed explanation and paid zero penalties. He didn’t get lucky-he followed the rules.
How to File Correctly
If you need to file now, here’s how:
- Identify all foreign accounts. List every exchange, wallet, or platform where you held crypto outside the U.S.
- Calculate the maximum value per account. Use month-end exchange rates from a reputable source like CoinMarketCap or CoinGecko. The IRS requires this. Don’t guess.
- Add them up. If the total across all accounts ever hit $10,000 in a year, you had to file.
- File electronically. Paper filings are not accepted. Use the BSA E-Filing System at FinCEN.gov.
- Keep proof. Save screenshots, transaction histories, and exchange statements. The IRS may ask for them.
Doing this yourself takes 8-12 hours per taxpayer, according to the AICPA. Most people hire a crypto-savvy CPA. Rates range from $350 to $600 an hour. Automated tools like CoinLedger charge $99-$299/year to generate the FBAR for you.
What’s Coming Next
The Treasury Department plans to integrate crypto data into the Common Reporting Standard (CRS) by 2025. That means foreign exchanges will automatically send your info to the IRS-no request needed. It’s like FATCA, but for crypto.
Expect more audits. More penalties. More court cases. The IRS is not backing down. And the clock is ticking for anyone who hasn’t filed.
If you’ve held crypto on a foreign platform since 2016, you’re at risk. Even if you didn’t sell. Even if you didn’t think it mattered. The law doesn’t care about your intent. It cares about your filings.
Do I need to file an FBAR if I only hold crypto on a foreign exchange?
Yes. If you’re a U.S. person and the total value of all your foreign financial accounts-including crypto on Binance, Kraken, or any other overseas platform-exceeded $10,000 at any time during the year, you must file an FBAR. The IRS now treats foreign crypto exchanges as financial institutions under the Bank Secrecy Act.
What happens if I didn’t file FBAR for crypto in 2021?
If you didn’t file and the IRS finds out, you could face a $100,000 penalty if they determine your failure was willful. Even if you didn’t know, you could still owe $16,536 per year for non-willful violations. The IRS has already begun enforcing this, with the first court case filed in January 2024.
Can I file FBAR for crypto myself?
Yes, but it’s complicated. You need to track the highest value of each foreign crypto account during the year using reliable exchange rates, combine them with any other foreign accounts, and file electronically through FinCEN’s BSA E-Filing System. Most people use crypto tax software or a CPA to avoid mistakes.
Does the IRS know about my foreign crypto accounts?
Very likely. Major foreign exchanges like Binance, Kraken, and Coinbase International now collect U.S. taxpayer ID numbers and report data to the IRS under FATCA agreements with over 110 countries. The IRS can cross-reference this with your tax returns. Ignorance is not a defense.
Is there a way to avoid penalties if I never filed?
Yes. The IRS offers two programs: Streamlined Filing for non-willful failures and Delinquent FBAR Submission for those who didn’t know. If you file past-due forms with a reasonable cause statement, you may avoid penalties entirely. But you must act before the IRS contacts you.
What if I have crypto on both U.S. and foreign exchanges?
Only foreign exchanges count for FBAR. U.S.-based exchanges like Coinbase.com or Binance.US are not subject to FBAR reporting. But if you had crypto on both, you still need to report the foreign holdings if the total across all foreign accounts exceeded $10,000.
How does the IRS calculate the $100,000 penalty?
For willful violations, the penalty is the greater of $100,000 or 50% of the highest balance in the account during the year. After the Supreme Court’s Bittner decision, penalties are assessed per report (per year), not per account. So if you had multiple accounts and didn’t file for 2022, you get one $100,000 penalty-not one per account.
Do I need to report crypto in my wallet if I control the private keys?
No. FBAR only applies to financial accounts held with foreign institutions. If you hold crypto in a personal wallet where you control the private keys (like a Ledger or Trezor), it’s not reportable. But if you use a foreign custodial wallet (like MetaMask connected to a foreign exchange), it may count.
Can I be audited for crypto FBAR violations years later?
Yes. The IRS has six years to audit FBAR violations if they suspect fraud or willful non-compliance. For non-willful cases, they typically look back three years. But if you never filed at all, they can go back as far as they have records-sometimes 10+ years.
What if I’m not a U.S. citizen but live in the U.S.?
If you’re a lawful permanent resident (green card holder) or meet the substantial presence test, you’re considered a U.S. person for tax purposes and must file FBAR for foreign crypto accounts. Non-residents who don’t live in the U.S. are generally not required to file.
